APPARATUS FOR THE DELIVERY OF A GIVEN QUANTITY OF LIQUID IN EXCHANGE FOR A COIN.

SPECIFICATION forming part of Letters Patent No. 389,909, dated September 25, 1888.

Application filed December 22. 1887. Serial No. 258,707. (No model.)

To all whom it 71mg concern:

Beitknown that I, HEINRICH STOLLWERCK, of the city of Cologneon-the-Rhine, in the Kingdom of Prussia and German Empire, have invented a certain new and useful Improvement in Apparatus for the Automatic Delivery of Liquids, of which the following is a specification, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to an improved apparatus which is intended to deliver a certain quantity of liquid, or of asolid substance,after a coin has been introduced into the said appa- 1 ratus.

In the accompanying drawings, forming part of this specification, Figure l is a sectional view of my improved apparatus. Fig. 2 is an elevation of the same at right angles to Fig. 1. Fig. 2 is a detail of Fig. 2. Fig. 3 is a sectional view of a modification of the improved apparatus. Figs. 4 to S, inclusive, show details of construction.

Referring to Figs. 1 and 2 of the drawings, A is a receptacle,and B a measure or measuringcompartment, which, like most of the actuating parts,are shown asbeing contained in a casing of the shape of a bottle. The receptacle A, which is to contain the liquid to be sold, communicates with the measuring-compartment B through an aperture, I), which is arranged to be closed by means of a valve, (1, controlled by the spiral spring (L The measure B is provided with an outlet, 0, which is controlled by a valve, (1, moved from its seat in an opposite direction to the movement of the valve a, the valve-rod d of the said valved forming a continuation of the rod a, carrying the valve a.

WVhen the apparatus is in its normal position, the valve a will be'open, while the outlet 0 of the measure B is closed by the valve d, which is held upon its seat by a spring, (2". It will be seen that by means of this arrangement asuitable mechanism brought to act with downward pressure upon the rod c of the valve a would at the same time both close the aperture I) by means of the valve a and open the outlet 0 by means of the valve (1, so that the liquid, having entered from the receptacle A 50 into the measure B and filling the latter,

would by the operation of the said mechanism be allowed to escape therefrom through the outlet 0, and through a tap, 0, connected therewith,into a glass or other receptacle held under the said tap c. The said mechanism, 5 which is put into operation by the insertion of a coin in any convenient and well-known manner, consists of a lever, f, fulcrumed atf, and carrying the valve-rod c and the connecting-rod g, pivoted thereto, the other end of which is pivoted to a bell-crank lever, h, connected to the bent lever 13, whose peculiar shape is bestse'en from Figs. 2 and 4 of the drawings, and which is fulcrumed to the bottom of the casing at i", Fig. 2, and provided with a slot or aperture, 6.

7c is an angular sliding bar, the free end of which corresponds to the size of the slot 6, and is arranged at such a distance from the latter as to cause the coin which is introduced between the lever i and the angular bar It to be held by the latter against that part of the leveri having the slot 1 as shown in the top view, Fig. 6. The angular sliding bar It has an extension, surrounded by a spiral spring, Z, and provided at its rear end with a projection acted upon by a cam, m, which is contained within the dummy-cock G and forms the lower part of the vertical pivot of the handle a. If there is no coin between the lever t and the So angular piece it, the outlet 0 cannot be opened by moving the cam on of the dummycock G by means of its handle a, as in this case the said cam will push the piece It clear through the slot t" of the lever t, as shown in Fig. 5 of the drawings. The lever t, and consequently the outlet 0 and its intermediate connections, will therefore not be operated, but will remain in their normal positions. If, however, a coin is introduced between the lever i and 0 the angular piece It, as shown in Fig. 6, and the handle a turned, the said piece It will press the said coin against the surface of the lever '5 and turn the latter on its pivot By reason of the inclined position which is thus given to 5 the surface of the lever t the angular piece 70 will now be out of line with the slot t" and its free end commence to bear against the surface of the lever 2', as shown in Fig. 7, when the coin will be released and drop down into a suit IOO able receiver. (Not shown in the drawings.) The pushingpiece 7c, now bearing against the lever 2', will turn the latter so that the bellcrank lever it will now be turned on its fulcrum and willpull down the rod 1, which will operate valve-rod a, and thus close the valve (t and open the valve (I. against the tension of the spring d. The contents of the measuringcompartment B will then flow out through the pipe of the tap c, as will be readily understood. lVhen the glass or other receptacle which is held under the said tap e is filled with the contents of the measure B and the latter emptied, the purchaser will take his hand from the handle a of the dummy-cock C, whereupon the spiral spring Z and the spiral spring (6'', e11- circling the valve-rod a and arranged between the receptacle A and the lever f, will cause the handle a and the angular piece 70, as well as the bell-crank lever h and the lever '17, to move into their normal positions, while the spring d will close the valve d and-raise the valve-rod a, now relieved of the pressure exerted upon the same by the operation of the lever i.

The valve-rod (1 may be provided at its up per end with a fixed collar, (1, so that the valve a may not be raised against the tension of the spiral spring c until it is in contactwith the said sleeve (1, in order to prevent the liquid from the receptacle A from entering the measure TB before the outlet of the latter has been closed, the said valve-rod (1 having in such case no fixed connection with the valve (Z.

The valve-rod a is made of the form of a tube, which above the sleeved is provided with a vent or air hole, 0, Figs. 1 and 8, for the purpose of establishing a communication between the outside air and the interior of the measuringcompartment, and thus to insure the flowing out of the liquid from the latter.

Fig. 3 shows a modification of the apparatus for automatically delivering samples of liquids, as hereinbefore described with reference to the accompanying drawings, the said modified apparatus being intended for use with barrels, casks, or receptacles of larger dimensions. This apparatus is screwed by means of the threaded sleeve 2 upon the tap q of the barrel, cask, or the like, and the measure B may be of any convenient size. The volume of the said measure may be regulated to any desired quantity by balls of glass or the like placed in the said measure. The coin t is inserted in the passage t, which will conduct it into position between the lever t and the angular piece 7;.

As will be readily understood, the valve-rod a may, in lieu of the dummy-cock C, be actuated by a suitable gear of wheels put in operation by a coin dropping upon a suitable lever and forcing down the valve-rod a by means of a suitable cam acting upon the connecting-rod g and upon the leverf, so as to close the valve (4 and open the valve (1. I also wish it understood that, without departing from the nature of my invention as heretofore described, I may combine the said dummy-cock (3 with the said lever i, for the purpose ol'deliverlng solid substances instead of liquids after the insertion of a coin into the apparatus. Instead of using the cam m, I may operate the said angular piece 7; by means of a button fastened upon the end of some suitable sliding bar, as will be readily understood.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the measuringvessel having an inlet and outlet opening, of the vertically-moving valverod carrying a downwardly-closing valve for the inlet-opening and an upwardly-closing valve for the outlet-opening, a pivoted swinging lever, t, having an aperture, i, connections between the pivoted lever and valve-rod, and a reciprocating bar, 7r, for swinging the lever when a coin is placed between said lever and bar, substantially as described.

2. The combination, with the measuringvessel having the top inlet and the bottom outlet opening, of the vertically-moving valvestem carrying a downwardly-closing valve for the inlet-opening and an upwardly-closing valve for the outlet, the belt-crank lever h, and a vertical rod, connected with the bellcrank lever and valve-rod, substantially as described.

3. In an apparatus for automatically delivering liquids in determined quantities, the combination, with a containiing-receptacle, and a measuringvessel connected therewith having inlet and exit openings, valves connected together and working in opposite directions for opening and closing said inlet and exit openings, a valve-stem, a pivoted bell-crank lever, h, and connections between said lever and valve-stem, the bent lever 13, having slot '11, the angular sliding bar 70, and the cam m, and dummy-cock or lever (J, for actuating the lever 11 and connected parts through the medium of a coin inserted between said bar and lever z, substantially as described.
